On quality of object-based video material

Object-based video coding is a fairly new topic and while quality assessment is a main part of traditional video coding it has not been investigated much for object-based material. Many quality assessment metrics have been published and some are widely used. If they can be used for object-based material as well is evaluated in this paper. The two most used full-reference algorithms and two promising no-reference algorithms have been tested. Only one of the no-reference algorithms correlates with subjective impressions and expected quality results. This algorithm unfortunately is very slow (over 8 min/frame).
